This feat is employed either separately, or in connection with the Driving Feat. It consists in the performer opening the combination safe of a hotel or some business establishment. In this case the Transmitter must know the combination perfectly, and his mental impressions acting upon the performer give him the cue to turn "right" or "left" or "repeat" as the case may be. Of course one must have cultivated a great degree of sensitiveness to mental impressions before he will be able to receive and respond to the direction impressions in this case. And yet almost any person by following the directions given in this work, and carefully and repeatedly practicing the various feats and demonstrations given herein, may be able to reproduce this feat of the professional performer, who is in constant daily practice, and who is able to devote his entire time to the work, as his "bread and butter" is concerned therein. Once the sensitiveness is gained, the details of the work are nothing more than those employed in any of the "finding" or "drawing" feats herein described and explained. THE OFFICE DETECTIVE FEAT. In this feat the public committee picks out an object on the desk, or about the office of some one of its members, the office being located some distance from the place of meeting. The performer then rushes along the public streets, dragging the Transmitter with him, until the office is reached, then up stairs, and into the room selected, and up to the desk, or other place, and lo! the object is found. Divesting this feat of all its sensational features, the student will see that it is merely a variation of the ordinary "finding" feat performed in the parlor. It creates a great sensation, but there is nothing more wonderful about it than about the simplest "finding" feat. THE POSTOFFICE FEAT. Another feat favored by some of the professional performers is that of having a letter placed in a post-office lock-box, the key of which is given the performer at a point some distance from the post-office. Rushing through the public streets, dragging the Transmitter with him, the performer finds the post-office in the usual way, and then locates the lock-box, into which he inserts the key and extracts the letter, thus triumphantly completing the feat. This feat, as every student will see, is merely a variation of the simpler feats manifested in a sensational manner for the purpose of public advertisement. THE FIRE-ALARM FEAT.
